Well riding a SouthWest Train on National Rail Service in England. Signed up for free wifi and Forum says I'm permanently banned. I assume problems with the IP address. I used my corporate VPN and lo and behold I'm posting .

Yep, I've been banned from the forum more times than you can imagine. If you find yourself with a heavy international travel schedule, drop me a PM and I'll get you some info on how to keep that from recurring.

Your number one option for personal security is a lifelong commitment to avoidance, deterrence, and de-escalation. When those fail, aim for center mass.
